A noninvasive mounting device (e.g., a large ring, table-fixed bridging bar) designed as a component of a surgical retraction system, intended to be placed/fixed around a surgical incision site and upon which retraction system blades/components are mounted to temporarily part tissue (e.g., hold the edges of an incision open) to expose internal tissues or organs for access during surgery. It does not include the invasive retraction blades/components (i.e., is not the complete system). This is a reusable device.
